Product introduction

It is a new automated testing equipment, it uses advanced electronic technology, the transformer is taken directly polar decomposition of the error signal, and after appropriate after the operation, the transformer points, phase error , quadrature error in the digital display. NAVAT transformer calibrator is simple, intuitive readings, measure quickly, can reduce energy consumption, reduce labor intensity; small size, light weight, easy to carry and field testing; instrument can be fixed at 5% Operating current (voltage) under testing; some old users asked Nanao Electric Wuhan Co., Ltd. produce this new generator testers, which can detect S-class current transformer and the secondary voltage of the voltage transformer calibrator 100/3V, then 1% of the rated instrument can measure the current transformer operating current the error; instrument in the detection process can be easily carried from the school at any time to ensure the accuracy of the instrument; critical components using imported components, stable and reliable quality, widely used in metering, power supply and other departments and transformer manufacturers, is to carry out transformer testing the ideal instrument.

Also called name

Transformer tester, PT calibrator, CT calibrator
